Unless you have specific reasons to do otherwise, disable Java but leave 
Javascript enabled. There is no practical relationship between these two 
languages and how they are implemented.

Java is only required for a few defined applications; certainly almost no web 
pages rely on it. Javascript, on the other hand, is used in many (most?) web 
sites and if you turn it off then lots of web sites will show unpredictable 
behaviour and many will be unusable.

Javascript has had no security implications, as far as I am aware, since its 
very early days maybe 20 years ago. It is intrinsically less likely to have 
security issues because, except in a few tightly controlled ways mediated by 
the browser, it has no access to any files on the host computer.

Java issues

[Severin Crisp]

I have been following the Java security items with interest and have disabled 
Java in Safari Preferences for safety at the moment.  
Should I also disable JavaScript?   I can not find any reference to Java in 
Firefox preferences.  
I can not find Java preferences in "others" though I have up to the minute 
10.8.2 and no updates outstanding that I can see, nor have I ever seen it in 
the past.  I know I have installed all Java updates as they appeared.
With Java NOT enabled, what should I expect not to work?  So far nothing has 
complained.   
I can find no Internet plugins for Java, only an alias to Java Applet.   
Comments welcomed!

Re: Question for the Gurus

[Neil Houghton]

Hi Peter,

Yes, there it was, thanks for that. I hadn't actually realised there WERE
java preferences (as opposed to the java settings in browser preferences) -
so hadn't thought to go looking for any (until I saw your post).


Something new to learn every day ;o)


Cheers

Yes, this has changed so much in recent years it's hard to keep track of it 
all. Have a look in /Applications/Utilities for Java Preferences if you can't 
find it System Preferences.

Re: Folders on external locked

[Rick Armstrong]

Hi Peter, When I get info on the drive, and into Sharing and Permissions - 
there is no check box, just read and write permissions which I have given the 
read and write on all. What I have done with the folder is copy to desktop then 
back onto the external, that fixes the no access icon on the folder, however 
there are a few jpeg images inside that folder that say I haven't permission to 
open and to contact the computer or network administrator for assistance.

I presume this is in Mountain Lion (and Lion?) only. I'm still running Snow
Leopard (10.6.8 with Software Update showing all current) and there is no
"java" in my system preferences.

When you Get Info on the drive itself, do you see at checkbox labelled "Ignore 
permissions on this drive"? If so, make sure it's unchecked.

I believe there were a handful of issues in the latest release still causing 
concern, but it seems these were manifesting on a handful of computers at 
Apple's head office! This was as late as last week. The question of using Java 
or not remains highly controversial. Certainly, you should at least turn off 
the Java OPlug-in in your web browser, since this will be principal vector for 
the nasties to get in, and probably the only one on a Mac. Regarding non-web 
use of Java, if you need it you need it. If you can't print without Java being 
active, you have little choice but to turn Java on or get a different printer.

To disable Java in Safari: go to Safari > Preferences > Security and uncheck 
the "Enable Java" option.
To disable Java generally, go to System Preferences > Java (it's in the "Other" 
group). If your version of Java is recent enough to be the Oracle version 
(which it should be) the Java Control Panel will open in another window. Click 
the "Java" tab, then the "View..."  button. Uncheck the "Enabled" option. Close 
all windows.
